to see some real amps ( considering power ha ha ha ) from you carlos!!!!
its a very nice thing to see someone who managed to produce quality reliability with simplicity and afordable cost to procced to biger machine .....

i am going to be one of the first to buy ..... to listen ....and ofcourse to abuse your amp in my small pa application

Nice amp design, I am pretty sure it will have great sound - see you have changed your opinion Self and are using some of his ideas. The better you amp gets the more ideas i see from Self there.Self does not spoonfeed all his knowledge to others, he only points you in the direction; you have to explore. I dont know whether you are aware that he designs comercial amps which are relatively cheap,have won various awards and with great sound for the price.

I view amp design a bit like hugh from aksa does, hormonic content very important (His amps overdo it a little bit, what he calls musical i call a tad of colouration,too sweat; i compare to the live real thing) and make some cash on the side modifying amps and cd players, my favourites are rotels. Relatively cheap, well built with excellent choice of parts that offer quite good sound for the money. They can become magic with some tweaking!!! The less thd and tim the better but always with a close eye on the harmonic content.

The amp i use is a middle of range 12 year old tweaked rotel which i have compared together with a couple of musicians (sister included;piano) to various amps (some big dollar high end) and including a aksa 55 belonging to a friend. This amp simply blows the aksa away, its in a different class. Some simple amps can be made to sound very good indeed, compensation is critical and component choice important.

I have a roughly built dx II, and a hint try 2sa1016k/2sc2362k for ltp and 2sa1406 or 7/2sc3600 or 1 for vas, even on this new design. Compensation can then be tweaked too and this is what hugh and now also you seem to have mastered.
Maybe ill try this one too later, but i have been playing around for last 9 months with a design similar to roender (i got my idea from ad817/ad797) have not fully mastered the sound yet, but have to say folded cascode gives clean fast and powerful sound. Roender has some excellent ideas, his input pair does sound marvillous and probaly his whole design too.

Nice to read your posts always some humor in them. I am portugese too but born bred and educated in same country as "Nordic".
